They aren't for sale yet, but at least it's all listed on the site now. Price and specs and whatnot. That's a good sign.
I personally am waiting to see if I should get the 65" P-Series or M-Series. there is a $500 difference, need to see some reviews to see if it is worth it. I'm not really a videophile or anything, either is going to be a huge upgrade from my current TV, but still want to make sure I get the best bank for my buck for gaming and movies.
